the 19th of September. On the 21st, all
arrangements having been completed, Mr. H.B. Renwick, leaving the
assistant commissary with only one man in the stationary camp, set off
toward the head of Rimouski. This course was pursued for six days, when
it became necessary to return for want of provisions, and the stationary
camp was reached on the 2d October. On this expedition the line of
exploration made in June up the Rimouski was intersected and the ground
traversed in July and August seen and connected with the survey, but
it was found impossible to penetrate along the height of land on the
western side of Rimouski to its head. On reaching the camp snow began
to fall, and the thermometer marked 18 deg. in the morning. All further
operations for the season in this direction were therefore at an end.
A portion of the line which divides the waters falling into the St.
John from those falling into the St. Lawrence remained in consequence
unsurveyed. It can not, however, be said to be absolutely unexplored,
for it was seen from the eastern side of Rimouski, presenting the
appearance of a range of hills at least as elevated as any on the
boundary.

18. Mr. Lally having received a fresh supply of barometers on the
evening of the 23d, resumed his survey of the height of land on the 25th
September, and reached the camp of the commissary on Mount Biort on the
2d October, having surveyed and leveled the intermediate dividing ridge.
The party of H.B. Renwick descended the Abagusquash and Tuladi, and,
crossing Lake Temiscouata, reached the same rendezvous on the 5th
October. The interval was spent by Mr. Lally's party in clearing a space
for a panoramic view on the summit of Mount Biort.

19. The commissioner, having superintended in person the equipment and
embarkation of the parties of Messrs. H.B. Renwick and Lally on Lake
Temiscouata, returned to the river Du Loup for the purpose of making
astronomic observations. These being completed, he visited and conferred
with the parties of his colleague, A. Talcott, esq., on their way to the
height of land southeast of Kamouraska. Here he made arrangements for
the junction of the two lines on the Temiscouata portage. He then
proceeded to the camp of the commissary on Mount Biort, and there made
provision for the completion of the residue of the line in the vicinity
of the portage. He also selected points of view for the use of the
daguerreotype and camera lucida, and, being unable to d
